Unrealized losses are generally due to changes in interest rates. The Company has the intent to hold these securities either until maturity or a forecasted recovery, and it is more likely than not that the Company will not have to sell the securities before the recovery of their amortized cost basis. Due to the nature of the investments, current market prices, and the current interest rate environment, the Company does not consider these securities to be other-than-temporarily impaired at December 31, 2022 and 2021.
The amortized cost and approximate fair value of investment debt securities, by contractual maturity, are shown below as of the dates presented (dollars in thousands). Actual maturities may differ from contractual maturities due to mortgage-backed securities whereby borrowers may have the right to call or prepay obligations with or without call or prepayment penalties and certain callable bonds whereby the issuer has the option to call the bonds prior to contractual maturity.
